To a-ZZ ywium'i it may concern Be it known that l.. lvViLLLiii R.K'LNNEAR, a citizen of the United States, formerly a resident of NewCastle, Pennsylvania, and now a resident of the city, county, and Stateof New York, have invented certain new and useful Improvements Relatingto the Process of Separating Adheringrr Metal Sheets.

ln the formation of what is known in the art as a hot pack, the separateor individual sheets comprising the pack stick or here to each otherduring the operation of forming the packyso that heretofore, has beendiliciilt to separate the individual sheets from each other.

One oic the objects oi' in v invei'itioii is to so manipulate the hotpack that the adhesion between Ythe individual sheets' throughout theirentire area is broken or destroyed. so that the individual sheets arequickly and ellicieiitly seliniiated one troni the other with smallcost.

Other'objects will appear from the here inafter description.

The invention iu its broadest aspect consists in so manipulating the hotpack that each individual sheet of the pack throiiglr out its entirearea, will have. an independent surface niovenient or i'uliliing actionhackward and forward with. respect to an afljaceiit sheet. thusdestroying the adhesion hetweeii the individual sheets.

More particularly the invention consists first in corrugatingr orshaping the pack throughout its entire ,area into a siinions conton'rand then progressi velir and repeatedly reversingr the position olE thecontours and changing" the crests and the. depressions o'li` theci'ii'rufrations oi' contours.

Still more particularly the invention consists first in coiiugating oi'shaping the pack throughout its entire area into a sinuous contour andthen progressively and repeatedly reversing the position of the contoursand progressively changing the crests or depressions of thecoi'rugations or contours by causinga .relative inovcnient between thecorrugated hot pack and a sinuous or tortiiouslmssage through which thepuel( extends.

The invention will he more fully linderstood from the hereinafterdescription.

Any suitable apparatus may he employed for carrying out the invention,but I will now descrilie a Amachine which l have found to heparticularly useful tory this purpose.

T he machine is illustrated in the aecompanying drawings forming a partof this.

specification, in which:

Figure l is a diagrammatic plan view of the lower portion of the machineshowing the corriigating dies at the middle of the niacliine andtakeaway rolls or dies at the hack or' the machine. Fig. 2 is a similarview to that of Fig. l with .the eorriigating ,rolls or dies drawn .outto the end offthe machine. Fig. 3 is e. cross sectional view of 8 isacross sectional View of the carriages r carrying tlie eorrugating rollsor forming dies assembled at the middle of the machine, or in theirinitial position, the upper dies .shown raised and the hot pack inposition between the dies. Fig. 9 is a similar View to that ot' Fig. 8with the upper dies lowered and the hot pack corrugated or formed intosinuous shape between the dies. Fig. 10 is a similar view to that `ofFig. 9 with the upper dies slightly raised from Ythe position shown inFig. 9. Fig. 1l is a similar view to that oi Fig. l0, showing one set ofdiesthose on the left-slightly removed from the dies on. the right. Fig.12 shows the dies onv the left moved still farther to the left and thedies on the right moved farther to the right from the position shown inFi. l1. Fifi. 13 is a view showing both sets oli dies still fartherseparated and moving to the right and left respective/ly.

Referring to the drawings. in which the saine reference characterindicates the saine part in the several views: The part niarked 20represents the hed plate of the machine and 40 the upper head thereof.'the lattebeing niovahle vertically 'toward and from the hed plate bysuitable means. notsiiown lait well known in the art.

Formed' on the bed plate are eliannels or gruideways 21 and 22, intowhichi extend the llanges or front .and rear edges 28 and 24,respectively, of ay series of vlower frames or carriages Q5. 26. 27 and2S. The lower part of .the movable head facing the hed plate is fill QLiemeer.

provided with channels or guide-,Ware {l} i.' i i and 42, into whichextend die liahgef; ci front and rear edges 43 and til respectively..

of a series of upper trames or carriage@ la, 46, 47 and 48, and by whichthe saidcai riages are suspended in'an ixiiertcd position on the head.The lower carriages may he and preferablj.' are provided with rollerffior Wide faced wheels '129, 29, i0 and 30.. and the upper carriages withSimilar wheels e9., and 50. These wheels talie. up 4the thriiiet or. thecarriages and vpermit the same to more more freely over the bed plateand aci-oste the face of the head, when the het pact; if.; beingoperated. on by the. dies in. the marmer hereinafter described.

Journaled in the lower carriages are rolls 31, 31, 39. and 32 and intit-Le 'upper carriagrgee are similar rolls 51, 51.,-52 and 52, whichintermesh with each other and act as dies to corrugate or form the hotpack into a sinueus shape. The surfaces ot the dice form Walls of atortuous passage and the hot pack and said Walls or have relativemovement after the pack hat beer. corrugated.

` Journaled in suitable bearings in the lower carriages intermediate therolle or dies 3l, 3l, 32 ahdl/n are sets of rollers; 33, and journaledin the upper carriages` in simi lar supports and intermediate the endsol' the rolls or dies 5l, fill, f2 and 5&2, are rollers 53. The rollers33 and 53 are arranged. in pairs and straddle the dies 3i, 3l, 5352, 32,

5,1 51 52 and 52 and act as incaricor rollers for said dies and preventthe dies from springing between their ends when pressure is applied tothe not puch in corrugating and treating the Same.

An suitable number of carragce 'may he used )ut I have shown tour upperand .tour

lower carriages and have arranged. them in pairs. Each lower pair isconnected by bolts 61 and G2 and each upper pair has bolts Sil and -82which pass respectively loosely through openings G3, and 6G and 82h St,85 and 8G in the adjacentends of the re Spectivecarragcs forming eachpair. llhc, bolts are headed at each end to permit the carriagestormix'lg each pair to be separated to a limited extent. ,t'iurroundingthe bolts are springe (3?, 68, S7' aad 88 which tend te separate thecarriagea of a pair. 'lhe adjacent ends of the carriages are providedwith recesses (39 and 89, into which the ende Aof the springs fit aridwhich permit the :springs to be com resi/ed therein so that the adjacenteudsjol) tl cani-ages maybe caused to abut or be brought clossctogether.

The carriages are so constructed and, the i olls or dies are so mountedwith reepcct to each other that when the head lowered the dies 5l, 5l,i2 aud will be moved, between the lower dies Ell, 5l, 32 and 3L n l s lwlth the centers of the dice on, a. etrzught line und with silllicicatclearance lieti-recu the adjacent faces or the dies to loro] :i spacebetween which the het paclc ie einen ed and corrugated or termed into acinema contour. as will more clearly appear 'l'icai Fig. il olf thedrawing.

.llecured to the bed plate in the path of' ii'ioremeiit et the wheels2li* are cani pla ia or bridges 75, and in the path of the wheele 30"'are caux plates or bridges 76. These cznne or buidgce are so locatedthat the wheels 29a and 30 will ride over them during certain movementsof the carriages and will raise the carriages 2G and 2 to cause s llland 3Q. to .rip the hot pack the dice` 5l and 52, the relative u'iotli,ol' the guidcwaye lvl and and the thickness oit' the l'laugee 223 and,being euch that the. said rarriages 2t) and. 27 may have a limited rc.ical moreiiient `for this 'pur-- pose.

hllounted at the rear ot tbe machine and adjacent to' the carrie f are:1. serieii of takeaway rolls 1.00 mid ifi, through which the paci: iscarried at er l operated upon by the lice `in the machine as' hereinabove desc `ied.

rlhe operatie of the machine 'for carry ing out my process, will now bedescribed: With all of the carriages at the center ci 'the maclrihe and'with the inner endey of the in iler carriages abutting or in closecontact as shov-:h in. llige. l, E.. i) and .1.0, and "a the head lilraised arid the upper dies r cl above the lower dicej as shown 'in Figs.2i and 8, a hot pack .A consisting oi a, pluralit',V oi" :Hillel-iegsheets o placed betuecu, the dies and carried by the upper and lowercarriages reeliiectively as shown. in Fig. (ii. the head ot thc machineis their .lowered or forced down wl'iereupoii the upper dice are .marredbetween tbe lower dice and the but parli. forced between the adjacentisurtace-m ol the tippe cud louer diese respectively ami the hot pecl;wirrugated or bent into :l sinuous contour torni throughout its cutis-clength as shown in Fig. i). The head lli is non' slightly raised whenthe dice carried by the said head. recede slightly and the grip upon thehot pech 'will be loosened, but the paci; will still be held in asinuous contour ae shown in Fig. 1l). coop. this operation takes place,the carriagee 253 aud elfi lor oreuuplo, are dra'wi'i to the left by thelinks Z0 and 90 whereupon there truc carriages :irc eeparated from the awjacent carriagce Elli and. alli aud as-the .strain coince ii'porl thebridges 75, the carriage :26 is raised, caus-` ing the rollers or thedies 3l carried thereby to grip the pack' against the dies 51 adjacentthereto and carried by the carriage 46. As soon as this gripping actiontakes place the carriages to the right ot' the ma chine are pulled tolthe right by the links .71`

and 91, the lirst movement of these carriages will cause the diescarried thereby to slip over the right hand portion ot the pack for ashort distance and until the'wheels 30 ride upon the cam platesor`bridges T6,

whereupon the dies 32 force or grip the pack against the dies 521carried by the upper carriage 47. By the time this gripping4 actiontakes place, the Wheels L9a have moved oli' of the cam plates 75 asshown in F ig. l2 and the dies 31L carried by the cai1- iiage 26 ungripth pack and the dies to the left continue to move to the left and wipeover or move over that portion of the surface of the pack to the lett.During this operation the dies to the right are moving to the right andas soon as the wheels 30 move oli' of the cam surface 76, the dies 322*ungrip the pack and the dies carried by the carriages to the right ofthe Inachine move or Wipe over the pack.

As the dies to the right and left recede from each other, theystraighten out the pack between the inner carriages and tend to flattenor remove the corrugations or sinuous contours as more clearly shown inFigs. 12 and 13.

VViping the dies over the pack after it has been corrugated, causes thepack to move through a sinuous path formed by the walls of the dieswhich progressively' change the positions oi' the crests and depressionsof the corrugations longitudinally of the pack and thus repeatedly andsuccessively bend the pack or form the corrugations alternately inopposite directions, whereby each'individual sheet of the pack is`caused to continuously move or creep backward and forward upon theadjacent sheet, thereby, destroying the adhesion between the adjacentsurfaces of the sheet throughout the entire extent of the pack.

In Figs. '5, G and T, have illustrated .diagramniatically on an enlargedscale, the operation of the dies on the hot pack and the relativemovement between the same, Assuming that the dies are moving to theright and are wiping over the pack with the crests of the corrugationsin Fig.v 5 at c, c2 and c3, and the depressions at ai', Z2 and da, whenthe dies have moved to the position shown in Fig. 6, that parto'the packwhich was c i moved to the position shown in Fig. 6, a nd when the dieshave moved to the position showi'i in lio.. 7 this part of the pack willbe at c' as shown in Fig. 7 and the other crests and. depressions willbe changing their positions relative to the rolls accordingly, and asthe dies wipe to the right, that part of the pack which was at the topot'N the dies and formed crests of the corrugations, will be transferredto the bottom of the dies and any particular point or arca on the packwill be gradually and continuously moving in the direction of the travelof the dies. The continued movement of the dies, it will be seen, thusprogressivelyand continuously changes the position of the contours ot'the pack and tends to straighten out the pack, thereby caiising theindividual sheets of the pack to be continuously moving or creeping oneover'the other throughout their entire areas, with the result that theadhesion between the individual sheets of the pack is broken ordestroyed, completely separating the individual sheets one from theother throughout their entire surfaces or areas. After the pack hasbeen. operated on as thus described and the adhesion between theindividual sheets broken or destroyed, the upper dies are then raised torelease the pack, whereupon the pack is passed transversely through themachine to the take-away rolls l( )1. which [latten or straighten outthe piled up separated sheets forming the pack.

Having now described my invention, what l claim as new and desire tosecure by Letters Patent is:

l. The process of destroying adhesion between metal sheets forming a hotpack, which consists in eorrugating the pack throughout its entiresurface, then'changing the positions of the corrugations by advancingthe positions of the crests and depressions of the corrugations alongthe longitudinal direction of the pack.

The process of destroying adhesion between metal sheets forming al hotpack, which consists in corrugating or compressing the pack into asinuous form throughout its entire surface, then changing the positionsof the corrugations by gradually advancing the positions of the crestsand depressions o't.' the corrugations or sinuosities along thelongitudinal direction of the pack while the pack is held normallyin afixed relative position.

5i. The process of destroying adhesion be-l tween metal sheets forming ahot pack, which con sts in compressing the sheets to forni corrugationstherein throughout their entire extent, then changing the positions ofthe corrugations by gradually changing the positions ci' the crests anddepressions of the 'corrugations along the longitudinal diin Fig. 5,will have arcanes movement between the'engaged portions of the pack andsaid circuitous :passageu A 19. The process of destroying adhesion in apacket sheets, consisting or treatingsuccessively different areas-oflthe outer portion ofthe pack by pressingsaid portions betweenmembershaving registering corrugated surfaces and then developing relativemovement between the pack and 'said members to. produce the e'ect ofdrawing 'the pack endvvise .through a circuitous path.

20. Theprocessof destroying adhesion in a pack of sheets, which consistsin treating dilferent .areas ofthe pack by pressing the pack betweenmembers having registering corrugated surfaces and then developingrelative movement between the pack and said members to produce the eectof draix` Ing the pack edgewise throu h a circuitons path which imartsrepeate and alternating bending o the pack, said areas being treatedin the order of their nearness to the` outside of the pack.
